You said there was one in the recent mail, but all we could find was some mail redirecting feature(see link below) that does NOT reward the sender. There is also nothing mentioned in the mail besides this, leading to further confusion between my friends and me, we've been searching and there's no mention of it anywhere, there's nothing ingame, in Web or anywhere else, not being able to start the game at all.

I'm really trying to help us both here, so please, tell me how to access it?
